Every 10 seconds a child suffers abuse, either physically or emotionally. Children who experience abuse often feel unloved by their parents and wish to escape, with some considering suicide. Those who survive childhood abuse frequently struggle with smoking, drinking, and haunting memories that disturb their present lives. Physical abuse involves physical aggression or injuries deliberately inflicted on a child by an adult, and can include bruises, broken bones, burns, and rough treatment endangering the child. Child abuse has multiple complex causes, and parents who abuse their spouses are more likely to also physically abuse children, though the relationship between marital issues and child abuse is complicated.
